using rv345: Why Does My Router Lose Its Configuration after Reboot?

[sanjeeth-pz]

hi,

im using rv345. why does my config lost after a reboot of this machine.

i had user config, LAN config, VLAn, access rules and many more. on a reboot after a power maintenance, looks like rv345 has reset its config. i had to redo the config from scratch. 

any workaround or action plan? thanks in advance.

Have you were saved your config to memory ??

Try below Solution..

Solution

The most likely reason why the router has bypassed the startup configuration stored in NVRAM is that the configuration register has not been set properly. To change your configuration register so that the router does not ignore or skip the startup configuration upon reboot or power cycle, complete these steps:

From the Router# prompt:

1. Type configure terminal , and press ENTER.

2. Type config-register 0x2102, and press ENTER.

3. Type end, and press ENTER.

To verify the configuration register change, type show version at the Router# prompt, and review your show version command output again. Look for the configuration register setting, which must show a new value upon the next reload. Here is an example:

Router#configure terminal 
Enter configuration commands, one per line.  End with CNTL/Z.    
Router(config)#config-register 0x2102 
Router(config)#end

Router#show version

Configuration register is 0x2142 (will be 0x2102 at next reload)

When the router is reloaded, the new configuration register setting becomes active.

Router#reload
System configuration has been modified. Save? [yes/no]: n
Proceed with reload? [confirm]

Your router now loads with the startup configuration, and the configuration register is set to 0x2102. Your configuration loads properly after the next reload or power cycle.

Thanks,

1. Type config-register 0x2102, and press ENTER.   These commands are applicable to IOS based devices not RV-series.

yes .. Thanks for correct me..

Configuration Register Setting Router Behavior

0x102	Ignores break 9600 console baud rate
0x1202	1200 baud rate
0x2101	Boots into bootstrap Ignores break Boots into ROM if initial boot fails 9600 console baud rate
0x2102	Ignores break Boots into ROM if initial boot fails 9600 console baud rate default value for most platforms
0x2120	Boots into ROMmon 19200 console speed
0x2122	Ignores break Boots into ROM if initial boot fails 19200 console baud rate
0x2124	NetBoot Ignores break Boots into ROM if initial boot fails 19200 console speed
0x2142	Ignores break Boots into ROM if initial boot fails 9600 console baud rate Ignores the contents of Non-Volatile RAM (NVRAM) (ignores configuration)
0x2902	Ignores break Boots into ROM if initial boot fails 4800 console baud rate
0x2922	Ignores break Boots into ROM if initial boot fails 38400 console baud rate
0x3122	Ignores break Boots into ROM if initial boot fails 57600 console baud rate
0x3902	Ignores break Boots into ROM if initial boot fails 2400 console baud rate
0x3922	Ignores break Boots into ROM if initial boot fails 115200 console baud rate

If the value you have for the configuration register is not in the table, then determine which bits are set in order to compute the value:

Bit Number Hex Meaning

00-03	0x0000-0x000F	Boots Field Parameters: 0x0000 - Stays at the system bootstrap prompt. 0x0001 - Boots the first system image in onboard Flash memory (EPROM). 0x0002-0x000F- Specifies a default netboot filename. Enables boot system commands that override the default netboot filename.
06	0x0040	Ignore NVRAM contents
07	0x0080	Disable boot messages
08	0x0100	Break disabled
09	0x0200	Causes the system to use the secondary bootstrap. This is typically not used (set to 0).
10	0x0400	IP broadcast with all zeros
5,11,12	0x0020, 0x0800, 0x1000	Console line speed
13	0x2000	Boots default ROM software if network boot fails
14	0x4000	IP broadcasts do not have net numbers
15	0x8000	Enables diagnostic messages Ignores NVRAM contents

how do i enable terminal to the switch

[Jitendra Kumar]

which switch taking about ??

if you looking for an RV router terminal to enable ?? there is very limited on VR.

on a RV345 you go to Admin > Config management >  Source Filename & Destination Filename.  Change them via the drop down selection and to download select download to PC in the destination box.

The file is exported as an xml file which means you can edit the xml and upload with the changes you want.  You should be able to keep one as a template and modify this xml file for every new client including static dhcp clients.  It's pretty lengthy and appears to have every page of cofigs which obviously would make sense. 

You can refer below discussion.
